We have developed a simple, straightforward and highly efficient multi‐component one‐pot
synthesis of 2‐amino‐3‐cyano‐4H‐pyrans and pyran‐annulated heterocyclic compounds …

A novel efficient one-pot method for the preparation of 2-aminofurans was developed based
on multicomponent reaction of 3-hydroxy-4H-pyran-4-ones, α-ketoaldehydes and methylene …

A library of known and new 4-aroyl-pyrano [3, 2-c] chromenes have been synthesized
through the one-pot, three-component reaction of 4-hydroxycoumarin, aryl glyoxals, and …

Multi‐component reactions (MCRs) have gathered much attention recently due to their
superior efficiency, exceptional selectivity and simplicity. Synthesis of various compounds …

Textile waste made of post-consumer 100% polyester (PES) made of polyethylene
terephthalate (PET), is complicated and contains chemicals and colorants, thus recycling is …
